My twins react very positive to classical music. They are calmer, more relaxed and sleep faster one. However, this applies not only for the present album on which personally annoy me some "popular songs" that you have already heard a hundred times in advertising or as a soundtrack. Even better look at my little quiet piano pieces by George Winston or Ludovico Einaudi. Most often I am currently using the piano music of "Piano Melancolia". It works very well and also like my husband: Relaxation Music Piano - Soft piano music for relaxation and regeneration Part II
